1. A method for providing an output response from a physical system, the method comprising:

  • selecting a command input to be applied to a physical system having a fundamental natural frequency (fn);

    obtaining an acceleration frequency spectra of the command input;

    determining whether the robustness of the command input meets or exceeds a desired level of robustness based on the width of a frequency notch in the acceleration frequency spectra; and

    applying the command input to the physical system to obtain an output response if the robustness of the command input meets or exceeds the desired level of robustness.
